But her real adventure began with the events that led to her first book, Tuk-Tuk to the Road; the story of her journey from Bangkok to Brighton in a bright pink, three-wheeled Thai taxi.

The project began as a way for Antonia and her friend Jo to raise £50,000 for mental health charity, Mind, and culminated in their best-selling book, published in 2007.

However, the experience gave the budding explorer and writer a taste for the road, and she wasn’t about to stop there. Her next venture into travel writing, A Short Ride in the Jungle: The Ho Chi Minh Trail by Motorcycle, was published in 2014, and details the two-month trip the “veteran of ridiculous adventures in unfeasible vehicles” took around the jungles of Vietnam, Laos, and Cambodia.

Miss Bolingbroke-Kent’s most recent travel epic covers her time spent in the north-eastern corner of India. Arunachal Pradesh clings to the mountains in the far-east of the country, and the region is, even now, largely unmapped.

Setting out to chronicle this forgotten corner of Asia, she travelled some 2,000 miles. The book records her encounters with shamans, lamas, hunters, and opium farmers; visits to tribal festivals; and experiences listening to long-forgotten stories from the Second World War. It reveals her discovery of a world and a way of living on the cusp of changing forever.

The Book Hive, in Norwich, hosted the launch event, on Thursday, July 13.

Land of the Dawn-lit Mountains is published in paperback by Simon & Schuster UK. It retails at £9.99.
